Steelers center Maurkice Pouncey (high ankle sprain) has been officially ruled out for Monday night’s game. He did not practice all week and was considered unlikely to play. Doug Legursky will start at center, while Trai Essex gets the start at LG. Also out for the Steelers is wide receiver Emmanuel Sanders and linebacker Chris Carter. Jerricho Cotchery is expected to be the No. 3 receiver. Sanders foot injury has become a season long issue. Ben Roethlisberger is officially listed as questionable.  Troy Polamalu practiced today and is probable.
